Thisinvention relate'sfto scissors; object of the invention is thepro;vision of a vpair of scissors in which the blades are 'movably connectedto the shanks ,6 with the blade being curved on an are-of a circlewhereby the hair will be cut'dir'ectly instead of being forced at anangle to the shearing edge, thus preventing unevenness i In the drawing:Y I. v Figure 1 is a view in -eleivation of a pa r 30 of scissorsconstructed inaccordance with 1 r the principles of my invention, Figure2 is an end View in, elevatl n of r, v

A further object of the invention is the provision of a pair of scissorshaving shanks pivotally connected together and with blades removablyattached with the shanks, the connections between the blades and shanksco-operating to 'maintain' the pivotal' connection ofthe shanksinoperative relation.

This invention will be best understoodfrom a consideration of thefollowing detailed descriptiomin view of the accompanydrawings forming apart of thespecification; nevertheless itis to be understood; that theinvention is not confined-to the: disclosure, being susceptible of' suchchanges and modifications which shall define no material departure fromtliesalient features of the invention as expressed inthe appendedclaim.

A blade 45 has flanged portions 46 which engage over the edges of theshank 11 and when. the screw 28 is rotated sufliciently the blade willbe clamped to the shank 11 and secured in place. The lower end 47 of theblade 45 engages the shoulder 27- of the lower end 49 and the blade 40engages a shoulder 46.

A plate 50, shown more Fig; 10, has a notched portion 51.adapted toengage the annular portion This plate is fitted between the edges of theflanges 41 and a similarly constructed plate is fitted between the edgesof the flanges 46 of the blades 45- to cover the heads of the screws 21and 28.

When it is desired to remove the blades for the purpose of replacing thesame it is only necessary to remove the plates 50 and loosen the setscrews 21 and 28 whereby the blades 40 and 45 may be slippedrespectively from the shanks 10 and 11.

I claim:

A pair of scissors comprising a pair of shanks, blades removablyconnected with the shanks, said blades having flanges embracing theshanks, set screws carried by the shanks and engaging the blades forclamping the flanges to the shanks, a pin secured to one shank andprovided with a flange, shank having a recess to receive said flange,the last-mentioned flange being engaged'at diametrically opposite pointsby the flanges of the blade which embraces the shank having L therecess, plates provided with notches to receive the pin and having theedges thereof frictionally co-acting with the edge of the flanges in ablade.
